Which of the following groups of fibres are not attached to alveolar bone ?
Correct answer: A. Transseptal
- A. Transseptal
- B. Horizontal
- C. Oblique
- D. Apical
Explanation
Transseptal fibres pass from the cementum of one tooth to the cementum of its neighbour, so they are not attached to alveolar bone. Horizontal, oblique and apical fibres all insert into the alveolar bone as Sharpey's fibres.
